Similar triangles are triangles that has all sides and angles to be equal. The value of x if , ΔGEF and ΔHEF are congruent is 28
<h3>Similar triangles</h3>Similar triangles are triangles that has all sides and angles to be equal. From the given diagram;
<GFE = <EFH
Given
<GFE = 60 degrees
<EFH = 2(x+2)
Substitute
2(x+2) = 60
2x + 4 = 60
2x = 60 - 4
2x = 56
x = 28
Hence the value of x if , ΔGEF and ΔHEF are congruent is 28

Answer:
Internal angle =
Number of sides = 18
Step-by-step explanation:
Given that:
We have a regular polygon with number of sides unknown.
Measure of an exterior angle of the polygon =
To find:
Measure of an interior angle and the number of sides of the polygon?
Solution:
Let us have a look at the relation of sum of external angles.
Sum of one internal angle and its corresponding external angle =
Internal angle + external angle =
Internal angle = -
=
Sum of all the external of a regular polygon =
All the external angles will be equal because it is a regular polygon.
Let the number of sides =
Therefore,
Therefore, the answers are:
Internal angle =
Number of sides = 18
